  1. 1. Diagnostic PCR for the Detection of Yersinia enterocolitica and Salmonella in the Food-Chain: Reliability of PCR Performance

    Författare :Rickard Knutsson; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Kemiteknik och kemisk teknologi; Chemical technology and engineering; real-time PCR; YPCE medium; Enrichment PCR; DNA polymerases; PCR inhibitors; pre-PCR processing; Salmonella; Diagnostic PCR; Yersinia enterocolitica; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : This thesis deals with the methodological advances of diagnostic PCR including reliability of PCR and pre-PCR processing of food and feed samples. Diagnostic PCR has been greatly improved by the introduction of the second generation of PCR, so-called real-time PCR. LÄS MER

  2. 2. Quantitative detection of bacterial DNA in whole blood in bloodstream infection

    Författare :Ingrid Ziegler; Kristoffer Strålin; Paula Mölling; Magnus Rasmussen; Örebro universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bloodstream infection; bacteremia; sepsis; DNA load; quantitative PCR; droplet digital PCR; 16S rDNA;

    Sammanfattning : This thesis aims to increase the knowledge on how quantitative PCR can be used in the diagnostics of bloodstream infections, with an emphasis on quantitative elements.In Papers I and II, we evaluated quantitative data from two commercial PCR tests for pathogen detection directly in blood, Magicplex Sepsis (I) and SeptiFast (II), from patients with suspected sepsis.

  3. 3. Pre-PCR Processing Strategies for Quantitative Detection of Food-Borne Pathogens using Real-Time PCR

    Författare :Petra Wolffs; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DNA polymerase; sample treatment; pre-PCR processing; real-time PCR; Food-borne pathogens;

    Sammanfattning : Since the development of real-time PCR, the technology has been widely applied in the field of diagnostics. In comparison with conventional PCR it has opened up the possibility of accurate quantification of microorganisms in clinical, environmental and food samples. LÄS MER

  4. 4. Development of Real-Time PCR Based Methods for Detection of Viruses and Virus Antibodies

    Författare :Amal Elfaitouri; Jonas Blomberg; Helene Norder; Uppsala universitet; []
    Nyckelord :Microbiology; Real-time PCR; broadly targeted PCR; degenerated PCR; rTth DNA polymerase; thermolabile UNG; QPIA; IgM; Mikrobiologi;

    Sammanfattning : Quantitative real-time PCR (QPCR) technology has been very useful for diagnosis of viral diseases. QPCR has recently reached a level of sensitivity, simplicity, and reproducibility which allows a large number of samples to be screened rapidly, make it a suitable tool for the clinical virology diagnostics.

  5. 5. Kinetics Quality Assessment for real-time PCR

    Författare :Tzachi Bar; Chalmers University of Technology; []
    Nyckelord :kinetics quality assessment; PCR quality assessment; outlier detection; real-time PCR;

    Sammanfattning : For proper DNA quantification by real-time PCR, compared samples should have similar PCR efficiencies. This assumption might not be always correct, as suggested by hundreds of publications dealing with PCR inhibition. LÄS MER
